Description

The VN540-E, VN540SP-E, VN540-12-E are monolithic devices designed in STMicroelectronics VIPower technology, intended for driving resistive or inductive loads with one side connected to ground. Active current limitation avoids the system power supply dropping in case of shorted load. Built-in thermal shut-down protects the chip from overtemperature. The open drain diagnostic output indicates overtemperature conditions.
